Zac Efron is showing plenty of skin for his new movie -- we've seen the photos -- but there is one body part he's not willing to put on camera ... his butt.

Zac continued filming "Dirty Grandpa" down in Georgia, and it looks like there's a naked motorcycle scene -- but for some reason Zac's a little ass-shy. A butt-double was photographed stepping in for Efron.

Based on pics ... you'd think Zac would be happy to flaunt his cheeks, but instead it was the double's butt in the spotlight.

Carmelo Anthony's wife La La just totally one-upped the basketball star's promise of a Knicks championship ... by promising the whole world a look at two even more coveted trophies ... her boobs.

La La sat down for an interview with "The Breakfast Club" where she talked about a milestone in her exploding acting career -- an upcoming episode of the Starz show "Power" where she has her first sex scene.

That's when Charlamagne Tha God jumped in ... asking La La if the love scene would feature any 'freeing of the nipple' on her part ... to which she very gleefully answered, "Yes."

FYI -- She says it happens in episode four, which is set to air on June 27th ... so, you're welcome pervs.

EXCLUSIVE

Courtney Stodden's Hollywood destiny has finally been fulfilled -- she's recorded a sex tape, and it's about to go to the highest bidder.

Sources in the sex tape game told us 20-year-old Courtney recently shot her porn debut -- and it's being shopped around town. This ain't our first rodeo ... so, we figured the tape would eventually make it to the desk of Vivid Entertainment honcho Steven Hirsch, and ... bingo!

As for whether Vivid's bidding on the tape -- Hirsch wouldn't tip his hand.

But y'know the game by now -- Courtney has to sign off for the video to be legally distributed, and our guess is if Hirsch gets her to do that ... it's just a matter of time before there's a full release.

If there's any doubt she wants this out ... remember, this is the chick who couldn't shake out of her bikini top fast enough.

Bravo is pushing the line for basic cable, because Brandi Glanville'snipple made air.

It happened on the season finale of "The Real Housewives of Beverly Hills" Tuesday night. Brandi got into it with a few of the girls, and then Kim Richards crowed, "Before you go any further, your nipple is hanging out."

This clearly wasn't a mistake, since the show was edited and Kim's remark was right there for the editors.

Oprah Winfrey is holding the yard sale to end all yard sales -- in the form of a massive online auction -- and the items up for sale reveal ... Oprah's a little bit of a freak.

Look past her run-of-the-mill plates, tables, chairs, etc. -- and the thing that stands out is her abundance of nude artwork. For example, there's the set of four framed nude male mythological figures ... expected to fetch between $800-$1,200.

There's also a nude painting by Aristide Maillol ($8,000-$12,000), a few Ellie Dolgin nude statues (around $10,000), and a painting of a nude woman by Richard Edward Miller with an estimated worth of $80,000-$120,000.

There's also a weight set that looks barely used (no shade, just the truth) for about $500, a pen with Oprah's name on it for $50, and some kind of lamb sculpture that lays for about $2,000.
